-T he invent-ion relates to gas'kindling burners and the installation thereof in a fire-box for solid'fu'el.

.aAn object of the invention-is to provide a a gas kilidleruinstallation having a kindler burnerdisposable generally outside of a linings wall of. a firebox'and having a jet portion or the burner disposed through and along 'said'wallin substantially flush relation with the adjacent inner surface of the wall.

'Another object of the invention is to pro vide' for'the dis-posalof the kind er burner in a concealed and relatively cool space.

.A further object of the invention is'to provide a burner of simplified and generally improved structure for the use described.

Astillhfurther object-of the invention is to provide an improved lining wall for use -2 withbuirners of the character described.

aThe invention possessesother objects and features of advantage, some of whiclnwith the foregoing, will beset forth :in the -fol lowing description of 'the preferred form of'the:i11ve11t-ion which is illustrated in the drawings 1 accompanying and' forming part of the specification. It is to be understood, however, that variations in the showing made by. the said drawings and description 0 maybe adopted within'rthe scope of;the invention as set forth in :the claims.

"Figure is. a fragmentary plan section through one ofthe burners.

I Asherewith particularly disclosed, the de- 4 vice of our invention-is incorporated in a comter wall defining the top of a-warming closet or oven '13. As-here shown, the cooking top portionsa bove the fire-box is provided with an opening 14 in'which-a; griddle plate 16 or theflike is arrangedto be removablymounted in a welllunderstood' manner.

Preferably, the chamber 8-is divided-agenerally horizontally-by amember 17 toidefine a-combustion compartment-18 above the mem her and immediately below the-cooking top,

and: a fresh airsupply compartment 19 con stituting the remainderof thespace of. the chamber. Each .toprbirrneri 211 is disposed generally in the compartment 19 and opposite an opening 22in the member 17 .whereby airv inpassing from the compartment 19 will.

bedirected over the burner to provide the necessarysecondary air supply therefor. *As particularly shown, a conduit member 23 is mounted ateach opening forguiding the air over theburner thereat, it-beingnoted that the combustion of the burner jets takes place in'or-above the opening. The member 17, it Wilhnowbenoted, depends from atheco'okingtop portion above-ethechamber 8 and is provided-with an imperforate and substantially vertical side wall 24 at the edge thereof opposite the partition-walli 11, the wall 24 being spaced somewhat" fromthe wall 11 whereby the relatively cool fresh air compartment .19 extends the fullheight of the chamber adjacent the wall 11.

Upper-and lower kindler burners 27 and 28 respectively are provided for the fire box. Preferably, and asshown, the upper burner 27 isidisposed ito extendlmrizontally-above the plane of the horizontal wall 12 and with the greater port-ion thereof in the compartment 19, whereby a minimum heating thereof will occur. Extending toward and into the fire box from the burner a tapered rib portion 29 of the latter, which portion is preferably of uniform section throughout its length and extends horizontally substantially the full length of the lire box. The forward face 31 of the burner portion 29, it is noted, is plane and is arranged to be vertically disposed. A passage 32 is provided through the burner and such passage is connected at one end to a mixing chamber 33 of a suitable type. Jet perforations 34 are provided in the burner face 31, such perforations preferably being evenly spaced and communicating with the burner passage 32 which thus serves as a manifold for the various perforations.

The burner 27, it will now be noted, is particularly intended to be used both for igniting any solid fuel in the fire box and heating the overlying cooking top portion, and the jets of gas from the burner are directed generally horizontally for these purposes, whereby, when there is no solid fuel in the path of the jets, a horizontal sheet of fire may be provided beneath the cooking top which fire will be hottest centrally of the width of the fire box and extend substantially the full length thereof. The lower burner 28 is disposed within the fire-box space and at a level just above that of the fire-box grate 35 and inwardly of the position of the burner 27 whereby gaseous fuel from the burner may be delivered directly into any solid fuel at the bottom of the fuel receiving space of the firebox and the impeding of the space of the closet 13 is minimized. This burner, it is noted, is formed generally as is the burner 17 except that the jet rib 36 thereof is somewhat shorter than is rib 29 of the burner 27.

Coplanar and outwardly extending shoulders 37 are defined at the juncture of the rib portion 29 of the burner 27 with the burner body proper, and the similar shoulders 38 are provided on the burner 28. The wall 11, it will now be noted, is provided with slots 39 and 41 to respectively receive the jet ribs 29 and 36 of the burners 27 and 28 from the outside thereof with the wall disposed against said shoulders, whereby a seal is provided at the perforations. Since the shoulders 37 and 38 of the two burners are not in the same vertical. plane, the wall 11 is preferably offset inwardly at the lower burner 28 to permit the before mentioned engagement of the burner in the slot 41 thereof.

.\s is usual, fire resistant linings are provided for the sides of the fire-box. such linings including a lining member 42 for the wall 11. The member 42. it will be noted, is disposed generally inwardly of both of the burners 2 and 28 and extends substantially the full length of the firebox and between the grate and cooking top. To provide for the projection of the flame jets from the burner through the member t2, the latter is provided with an elongated slot -l3 opposite the burner portion 29 and arranged to have said portion w dgedly fitted therein with the jet face 3.1 of the bur disposed slightly outwardly of the general plane of the outer face i of the lining member. Preferably, and as shown, an outwardly extending flange +l:(i is provided about the edge of the slot 4-3, the outer edge of such flange defining a plane substantially coinciding with the plane of the face all. The flange s26, it is noted, operates to protect the burner portion 29 from such a disposal of fuel thereat as wlll clog the jeti' penings or burn the burner, and serves also to stiffen the member against buckling by heat.

lYhen, as is here shown, the burner 28 is disposed inwardly of a vertical plane through the upper burner 27, a lower portion 47 of the lining member 42 is offset inwardly at and above the burner 28 to accommodate the latter. Because of the close proximity of the burner to the bottom edge 48 of the member l2, the necessary opening for the jet portion of the burner is provided by an elongated notch 49 of suitable dimensions ex tending upwardly from the edge 48' and having the longitudinal edge 51 thereof engageable with the top side of the burner portion 36, The jet face 52 of the burner is preferably arranged to lie substantially in the plane of the inner face of the lining portion 47, and such portion is preferably also pro vided with an apron 53 which extends inwardly of such plane a sufiicient distance for its cooperation with the grate 35 to generally prevent a lodgement of fuel. directly against the burner face In elongated lnirners of the present type and in which a supply passage for the various jets arranged to be supplied with gas only at one end thereof, difficulty is usually met in insuring a proper supply of gas to the jets nearest the inlet end of the passage, since the movement of fuel across the jet opt-nings tends to create a suction and so decreases the gas pressure at said openings. The burners 27 and 28, it will now be noted, are arranged to overcome this difiiculty by reason of cer tain novel features of design incorporated therewith, the application of such features to the burner 27 being disclosed in Figure A portion 54 of the burner passage 32. it will now be noted. extends within and along the burner rib portions and the passage is of generally increasing section toward the inlet end thereof. The burner portion connecting the mixer to the rest of the burner provides a passage portion 56 which is connected to the passage 32 in offset relation to the passage portion 54 whereby the end of the latter nearest the passage 56 inlet is out of the direct line of flow of gas from such passage, and a pocket containing relatively quiet gas is thus defined against the end wall 57 of the passage portion, such wall being continued to an intersection with the wall defining the adjacent side of the burner portion 55. The influence of the pocket defined in the manner now described, has, however, not been found sufficient to insure the desired complete delivery pressure of the gas at the associated jets, and means are accordingly provided for increasing the effect. Accordingly, and as here shown, a baffle wall 58 is provided across the burner, such wall having its outer face 59 extending longitudinally forwardly from the end wall 57 in parallel and substantially coplanar relation with the shoulders of the burner. In burners proportioned in the manner here shown, it has been found necessary to extend the partition to lie opposite at least the first several jet perforations, it being noted that the location of the end of the partition depends on the particular design of the adjacent burner pol' tions.

We claim:

1. In a burner of the class described, a body having a rib portion extending therealong and arallel therewith and provided with a row of aligned ports in an outer portion thereof, said body having a longitudinal gas distributing chamber defined therein, and said rib portion having a longitudinal chamber defined therein communicating with said ports and forming a lateral extension of and communicating with said first chamber substantially along the entire length thereof, said body being provided at an end of its chamber with an inlet passage, and a battle wall extending inwardly from the end wall of said rib at said inlet passage to separate said chambers for a relatively short distance from said end.

2. In a fire-box for solid fuel, a gas burner disposed longitudinally along a side of the lire-box and having a tapered rib portion of uniform section horizontally directed inwardly therefrom and providing an aligned row of ports, and a lining member disposed in front of said burner and provided with a longitudinal slot to receive said burner portion in substantially flush relation with the inner side thereof, said slot being closed by said rib portion.

3. In a fire-box for solid fuel, a gas burner disposed longitudinally at a side of the fire box and having a tapered rib portion of uniform section and providing a plane outer edge having aligned ports therein extending along the burner and directed horizontally inwardly therefrom, a lining member disposed opposite said rib portion and provided with an opening for the fitted reception of said rib portion of said burner, said rib portion being arranged to extend slightly beyond the outer face of said lining member, and a flange portion extending outwardly from said face of the lining member to extend at least as far therefrom as the plane of said rib edge, said iopening being closed by said rib portion.

In testimony whereof, we have hereunto set our hands at Oakland, California, this 3rd day of October, 1927.
